摘要
为探索机械播种条件下,旱地小麦最佳的播种方式和最适的播种量,2015年秋季采用免耕宽幅匀播、宽幅匀播(非免耕)、免耕沟播和常规条播(非免耕)4种播种模式和150,187.5,225 kg/hm^2等3个播量,在孟津县白鹤镇范村旱地进行大区对比试验。结果表明,常规条播(非免耕)产量最高,免耕沟播省事省工,出苗齐全;4种播种方式除宽幅匀播外,均以播量225 kg/hm^2产量最高;在机械收获的情况下,调查所得理论产量等同于实际产量,不必再进行85%折损。
To find out a best sowing style and sowing method, as well as suitable seed amount under the condition of mechanical sowing, an experiment and demonstration on wheat sowing mode was conducted in a dry land in Fancun village, Mengjin county in autumn 2015. Four sowing modes（no-till broad-row drilling, broad-row drilling, no-till furrow sowing and traditional drilling）and three seed rates（150, 187.5, 225 kg/hm^2）were selected to be tested. The results showed that the wheat with traditional drilling method and225 kg/hm^2 seed rate had gotten the highest yield, while no-till furrow sowing would save time and labour, increase the rate and evenness of emergence as well. The theoretical yield drown from the scientific investigation before harvest could be regarded as the actual yield under the condition of mechanical harvesting, without need to times 0.85.
